“More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

To improve water conservation install a rain sensor, it turns off your irrigation when it rains. Use a weather-based controller. The use of smart controllers can reduce water usage 24% a year on average. Learn about available rebate programs ...

Maximum power point tracking system is widely used to maximise output power of photovoltaic array. A crucial issue of this system is an algorithm of maximum power point seeking. Well–known perturb and observe technique is optimal solution in terms of the ratio of cost and efficiency. However, this algorithm has some disadvantages such as oscillation around a maximum power point and decrease in ...

Calibration of the X-band LAWR (Local Area Weather Radar) is traditionally based on an assumed linear relation between the LAWR radar output and the rainfall intensity. However, closer inspection of the data reveal that the validity of this linear assumption is doubtful. Previous studies of this type of weather radar have also illustrated that the radar commonly has difficulties in estimating ...

The past decade has been one of unprecedented weather extremes. Scientists of the Potsdam Institute for Climate Impact Research (PIK) in Germany argue that the high incidence of extremes is not merely accidental. From the many single events a pattern emerges. At least for extreme rainfall and heat waves the link with human-caused global warming is clear, the scientists show in a ...

Municipal wastewater treatment plant (WWTP) influent is typically dependent on diurnal variation of urban production of liquid waste, infiltration of stormwater runoff and groundwater infiltration. During wet weather conditions the infiltration phenomenon typically increases the risk of overflows in the sewer system as well as the risk of having to bypass the WWTP. Combined sewer infrastructure ...

This paper presents an overview of the University of Western Macedonia's (UoWM) operational model for predicting the prevailing meteorological and air quality conditions on a high resolution (2 × 2 km²) scale. The MM5 – SMOKE – CMAQ has been suitably parameterised with respect to the particular geographical and climatic characteristics of the region of West Macedonia. The system is designed to ...

From the 22nd until 27th August 2005, the northern Alpine region was hit by severe floods. The floods occurred in tributaries of the Rhine River in Switzerland and Austria (Vorarlberg) and in several tributaries of the Danube River in Germany (Iller, Lech, Isar), Austria (Lech, Inn, Mur, Drau/Drava, Raab/Raba) and Hungary (Mur and Raba/Raab), as well as in the German part of the Danube. The ...

Introduction The worldwide market for temporary enclosures has steadily increased over the last two decades as facility owners, engineers and contractors recognise the safety benefits and cost-effectiveness of installing temporary enclosures. Apart from minimising weather-induced delays to a project, scaffold sheeting enhances site safety by preventing debris and small objects from falling ...

Sonoma Technology, Inc. (STI), with support from the Bureau of Ocean Energy Management, is leading a unique partnership of corporate, government, and university researchers to develop a marine environmental observations program in the Gulf of Mexico. The primary goal of this project is to develop a framework of advanced offshore measurements to support emergency response, oil and gas exploration ...

ABSTRACTAn extensive water quality modeling effort for the City of Columbus Long Term Control Plan (LTCP) was performed in order to evaluate future scenarios to abate combined sewer overflows. This modeling effort was supported by a massive data collection program and employed three different models to analyze the receiving streams. Once the models were selected and calibrated, continuous annual ...

Data from two unrelated pilot-scale submerged membrane bioreactors (SMBRs) studies are presented. Both SMBRs treated wastewater from combined sewer systems on the west coast of the United States: a flat sheet Kubota SMBR in Seattle, Washington (KC SMBR) and a hollow fiber Zenon SMBR in San Francisco, California (SF MBR). The SF SMBR was operated for a total of 834 d, through 3 rainy seasons, and ...

As extreme weather events like wildfires, heat waves, downpours, and droughts continue to make headlines in the United States and around the world, many have wondered what their connection is to climate change. A new report sheds some light, firmly drawing correlations between several extreme weather events in ...

Rochdale South is a predominantly residential suburb south of the Queensland capital city of Brisbane. It has a total population of 10,680 and a sewerage system catchment area of 580ha. The sewerage system includes five pumping stations which forward sewage flows to a downstream treatment plant. Rochdale South comes under the jurisdiction of Logan City Council, and Logan Water is the body that ...

In the context of real time (online) decision support systems for nuclear installations, atmospheric dispersion and deposition has to be calculated for a mesoscale area. Typically, the wind field in this area is influenced by topography. Therefore, simple Gaussian type modelling is not appropriate. Initiated and funded by the Bundesamt fur Strahlenschutz, simple (diagnostic mass consistent) flow ...

Doppler SODAR Operating similar to a sonar the Doppler SODAR (Sonic Detection and Ranging) directly measures the atmospheric wind speed and direction at multiple altitudes simultaneously. These systems utilize the Doppler effect imposed on the received acoustic signal echoed by the atmosphere for the wind measurements. The Doppler effect is the common observation that the acoustic signal ...

Forecast-based flow prediction in drainage systems can be used to implement real-time control of drainage systems. This study compares two different types of rainfall forecast – a radar rainfall extrapolation-based nowcast model and a numerical weather prediction model. The models are applied as input to an urban runoff model predicting the inlet flow to a waste water treatment plant. The ...

This study was a first attempt to portray the effects of land use and climate changes (CCs) on the hydrologic system in the Lamtakhong Basin in northeastern Thailand, which has been disturbed by various human activities, making it difficult to determine these impacts on hydrologic conditions. The hydrologic Soil and Water Assessment Tool model was set up with land use and soil data of 2002 and ...

Depleted uranium (DU) from the military testing and use of armor‐piercing kinetic energy penetrators has been shown to accumulate in soils; however, little is known about the toxicity of DU geochemical species created through corrosion/weathering. The purpose of the current study was to assess the toxic effects and bioaccumulation potential of field‐collected DU oxides to the model terrestrial ...
